However, as observational techniques that used to be restricted to research applications are entering operational mode, it is becoming possible to routinely measure evaporation and soil moisture ...
When water molecules do this, they change from liquid water to water vapor – a gas. This changing from a liquid to a gas is called evaporation. Heating a liquid causes the water molecules to move ...
And this process is called evaporation. When a gas cools down, it can change state back into a liquid. So when the warm steam hits the surface of, say, a cold mirror it turns back into water again.
